Response to some papers sent to R.A.S.
On the observation of sun spots.
More on the construction of a good optical eyepiece for solar observations [see FH's 1864-4-27].
Would like FH to study a phenomenon that JH has noticed on the sun's disk and that has no connections with sun-spots.
Proposes to travel to visit FH next day to observe the sun with him.
Details about sunspot observations.
Returns a paper of Mr. Stobart, which deals with astronomical knowledge of the early Egyptians.
Expressing sympathy on the illness of Margaret Louisa Marshall (JH's daughter). Would like to hear the latest news by the bearer. Would JH append his name to the enclosed form.
Comments on the sun spots he has been observing, and some new phenomenon. Any chance of a visit from JH?
Has returned James Nasmyth's letter and has never seen Warren de La Rue's letter. Comments on Nasmyth's 'willow leaves.' Have been observed at Greenwich Observatory. Thanks for his remarks on the best kind of eye-piece.
Hopes the JH's are all well. Would like an eye-piece made by Mr. Cook[e] or any leading optician on the principles of JH as laid down in his paper in R.S.P.T. Shall he refer the optician to this paper?
Is grateful for his communication on the proposed solar eyepiece. Will call round on his way to town to ascertain if he can leave the manuscript with [Thomas?] Cooke, the instrument maker, so that he can have some idea of the work involved. James Nasmyth will pay attention to screen projection.
Is uncertain if he has detected the lightlines on the solar surface to which JH has called attention, but there does seem to be something unusual there. No sun spots are visible just now.
Regrets he was out when JH called. Thanks for the elegant verses. Will be moving shortly to a place nearer London, which promises much. Gives notes on some more sun spots, which he has recently observed.
Much obliged for his kind notes on sunspots; there has been a wonderful variety lately. Will make a study of the Julian dates. Can see the Crystal Palace fireworks splendidly from his house.
Drawing of 'the singular mottled appearance of portions of the Sun's disk ... March 19th 1864'.
